The Lowdown
Alright, Rusty here. Let’s get you the lowdown on Kennebunk Beach in feet and miles per hour.
First week and a half? Forget it. The swell is tiny, the wind is onshore or cross-shore, and the wave energy is weak—most readings are in the double digits.
Starting Monday, August 24th, you’ve got a knee-high 0.8m wave (that’s about 3 feet) with a 7-second period out of the SE, but the wind is blowing onshore at 15 km/h (9 mph) from the SSW. Just messy slop. That kind of scene lasts through the end of August and into early September.
Then, Wednesday morning, September 2nd, things finally turn. Offshore wind from the ENE at 15 km/h (9 mph), a clean 0.7m (2 ft) swell from the SE with a 13-second period, and moderate energy at 223. It’s barely surfable but at least it’s clean.
The real window is Friday, September 4th, and Saturday, September 5th. Friday morning: offshore NE wind at 25 km/h (16 mph), 1.1m (4 ft) swell from the SE, 12 seconds, energy 486. Friday afternoon stays clean with 1.1m at 13 seconds, energy 533. Saturday morning is the peak: 1.2m (4 ft), SE, 13 seconds, offshore NE at 25 km/h (16 mph), energy hitting 600. That’s your best bet.
Water temp is 19°C (66°F), just a touch warmer than normal—nothing wild.
After Saturday it fades. Sunday the 6th has 0.9m (3 ft) and clean conditions but energy drops to 321. By Monday the 7th, onshore wind and chop are back.
So hang tight, save your energy for that Friday–Saturday stretch. It’s the only real opportunity in the 16-day run.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
